Sterilization & Sterile Barrier Manufacturing worked example

Gamma Dose Cost at 63% dose-mapped loading: a worked example in sterilization & sterile barrier manufacturing

This worked example runs the gamma dose cost numbers for a tougher week than the baseline: 63% dose-mapped loading instead of the typical 88%. Estimate gamma sterilization dose cost from pallet count, contract irradiation rate, dose-mapped loading, and dosimetry release fees.

The inputs for this scenario

  • Pallets Irradiated: 60 pallets (held at the documented default)
  • Irradiation Rate per Pallet: 320 $/pallet (held at the documented default)
  • Dose-Mapped Loading: 63 % (the input this scenario stresses; the baseline uses 88)
  • Dosimetry & Release Fee: 750 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total gamma dose cost = pallets irradiated x rate per pallet x dose-mapped loading + dosimetry & release fee.
  • Total gamma dose cost works out to 12,846 $ at these inputs, and this is the headline figure for the scenario.
  • Gamma dose cost per unit works out to 214 $ / piece at these inputs.
  • Variable gamma dose cost works out to 12,096 $ at these inputs.
  • Fixed gamma dose cost adder works out to 750 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where dose-mapped loading sits at 88% and the headline result is 17,646 $, this scenario comes in 27.2% below the baseline at 12,846 $.
  • Use it when quoting a gamma run, comparing sterilization modalities, or evaluating a contract sterilizer's rate card and minimums. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total gamma dose cost: 12,846 $ (headline result)
  • Gamma dose cost per unit: 214 $ / piece
  • Variable gamma dose cost: 12,096 $
  • Fixed gamma dose cost adder: 750 $
